论文摘要:
We examine the impact of information technology on systematic risk, the equity premium, and return predictability using national and state level NYSE ticker subscriptions that disseminate public firm-specific information. Annual variation in stock ticker subscriptions is not attributable to demographics, economic activity, or stock returns. Instead, this variation is positively associated with variation in trading volume. After controlling for liquidity, an increase in the number of stock tickers lowers both the average pairwise correlation between individual stock returns, hence systematic risk, and the equity premium (Pollet and Wilson, 2010). An increase in the number of stock tickers also reduces return predictability. We conclude that the adoption of information technology lowers systematic risk and the equity premium while enhancing price efficiency.
